Sean Kelly, a Lakeridge High School junior, helps set up his team's robot before practicing playing tic-tac-toe with it in the group's Lake Oswego workshop. While the team usually spends six to eight hours a week working on the robot, during spring break it was closer to six hours a day. Victoria Edwards/The Oregonian

The team's robot picks up rings to place on a tic-tac-toe board made of PVC pipes. Every year the FIRST robotics competition has a different theme, and this year's was "Ring it Up!" where teams built robots they control to play tic-tac-toe against others. Photo courtesy of Untitled-8.
